Paul Allen, latest billionaire bitten by the space bug

SEATTLE - Microsoft co-founder Paul Allen and aerospace
pioneer Burt Rutan announced Tuesday they're building a giant
airplane and spaceship to zip people and cargo into orbit.
But unlike traditional rockets and government spaceships, this
new commercial spaceship will drop from a high-flying airplane
instead of blasting off from a launch pad.

Allen and Rutan join a field crowded with Silicon Valley
veterans who grew up on "Star Trek" and now want to fill a void
created with the retirement of NASA's space shuttle. Several
companies are competing to develop spacecraft to deliver cargo and
astronauts to the International Space Station.

The duo won a prize in 2004 with a spaceship that went into
space but not orbit. Their new business model likely includes
tourism and satellites.

Their new plane will have a wingspan of 380 feet, longer than a
football field. The plane will carry under its belly a space
capsule with its own booster rocket, take off from a runway and go
high into the air. Then the plane will release the spaceship, which
will rocket to orbit.

This method saves money by not using rocket fuel to get off the
ground. Another older rocket company, Orbital Sciences Corp., uses
this method for unmanned rockets to launch satellites.

But Allen's rockets will eventually carry people. However, the
first tests, scheduled for 2016, will be unmanned. It should be
about five years before people can fly on the system that Allen and
Rutan are calling Stratolaunch.

The spaceship and booster will be provided by another Internet
tycoon, Elon Musk of PayPal, who has built a successful commercial
rocket.

Rutan will build the carrier aircraft which will use six 747
engines. The company will bill its method of getting to space as
"any orbit, any time," officials said. The company will be based in Huntsville, Ala. The Stratolaunch system will get built at the Mojave Air and Space Port, in Mojave, Calif. That is where Rutan's Scaled Composites is located, as well as the factory where Richard Branson's Virgin Galactic will be making its SpaceShipTwo rocket and WhiteKnightTwo carrier aircraft.
